If you have bought a ticket for Pokémon Go Fest 2025: Global, you'll notice a little note on the paid ticket that says you have increased shiny odds, without the game giving you any indication of what those increased odds actually are.
And while you can find shiny Pokémon during Go Fest without paying for the ticket, you'll find significantly fewer Shiny Pokémon compared to those who paid for the privilege of finding more. Granted, finding a Shiny Pokémon is no guarantee.
